The Lowdown
Alright, Rusty here. Let’s take a look at what’s shaping up for Jaconé over the next couple of weeks.
First up, the water temp is sitting at 73°, which is about 1° warmer than average for this time of year – just a touch on the mild side.
Alright, so the honest truth for the first few days is pretty grim. Tuesday and Wednesday are a write-off – onshore winds, rain, and messy conditions. The swell is there but it’s all wind-affected and choppy. Not worth paddling out for.
Things start to turn around on Thursday, September 3rd in the morning. We’ve got a clean 6ft S swell rolling in with a solid 11-second period, and best of all, an offshore ENE breeze at 12 mph. The combined wave energy is sitting at 821 (moderate) – that’s a solid amount of push. This is the first real standout of the forecast. The break is exposed to the SE but the swell is coming from the south, so it’ll wrap in nicely. Crowds can be around here sometimes, but with conditions this clean, it’s worth the company. This is the pick of the first week.
Friday, September 4th morning is glassy – I mean, dead calm with an NNE breeze at 3 mph. The swell drops a little to 4ft from the SSE, still an 11-second period, and the energy is 409 (moderate). It’s going to be fun, clean, and user-friendly. Not as much grunt as Thursday, but a lovely session for intermediates.
Saturday, September 5th morning is glassy again but the swell is tiny – 2ft from the SSE. The energy is only 123 (weak). It’s surfable but nothing to get excited about. After that, the weekend goes a bit average again with onshore winds.
Now, rolling into the second week, Monday, September 7th pumps up with a big 8ft SSW swell, but the wind is onshore and it’s raining – poor surf. That’s a lot of water moving (2746 energy – strong) but it’s messy. For the experts only, if conditions clean up, but it’s not looking good.
Tuesday, September 8th still has size (6ft to 7ft) and a long 12-second period, but the wind is onshore or cross-shore. The energy is huge (1285) but the quality is questionable. Not a standout.
Now here’s a promising one for the second week: Thursday, September 10th morning. Offshore ENE wind at 12 mph, a solid 6ft S swell with a long 13-second period, and energy at 1146 (strong). This is excellent for experienced surfers – the groundswell will be rifling down the line. The break is exposed, so that long period S swell will wrap in nicely. This is the second true standout of the forecast.
Friday, September 11th stays clean with offshore NE winds, but the swell drops to 4ft from the E, period dropping to 8 seconds. Energy is 317 (weak to moderate). Decent for a cruise, but not a standout.
Sunday, September 13th morning is glassy again – a 5ft S swell with 8-second period, energy at 469 (moderate) – but it’s a short period swell, so it’s a bit fat and weak. Surfable, but not the best.
Finally, Wednesday, September 16th morning is glassy with a long-period 5ft S swell at 12 seconds, energy at 943 (moderate to strong). That’s a lovely clean groundswell – perfect for a point or reef setup. The wind is dead calm, so it’s pristine. This is a nice late-period option, but it’s two weeks out, so keep an eye on it.
To sum it up: the best on offer is Thursday, September 3rd morning and Thursday, September 10th morning. The first one is cleaner and more accessible, the second one has more power for the experienced crew.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
